' EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 622,578, dated April 4, 1899.

Application filed August 5, 1898. Serial No. 687,780. (No model.)

To all whom it may concern/.-

Be it known that we, Approx GEORGE WET- TERGREN and RICHARD L. TREFFURTH, citizens of the United States, residing at Manhattan borough, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Extension-Tables; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention refers to an extension-table, the object being to easily convert a small bedroom table into a dining-table; and the invention therefore consists in the construction and combinations of parts, substantially as will be hereinafter described and claimed. In the annexed drawings, illustrating our invention, Figure 1 is a perspective view of our improved table before being extended, its form after extension being shown in dotted lines. Fig. 2 is a longitudinal section of the same. Fig. 3 is a longitudinal section of the table when extended. Fig. 4 is a cross-section. Fig. 5 is an enlarged detail view showing one of the locking-bolts. Fig. 6 is a detail perspective View of the tongue-and-grooved device at one end of the table-cover. Fig. 7 is a cross-section of the same.

Like numerals of reference denote like parts in all the figures.

2 denotes the body of a table, made hollow to provide a longitudinal compartment and having the usual legs 3, said body 2 being normally covered by the table-top 1, which is a single flat piece. The common appearance of the unextended table is shown in Fig. 1 in full lines. The top 1 is adapted to be slid endwise for a certain distance when an extension of the table is to be effected. The inner opposing faces of the longitudinal sides of the body 2 are formed for a certain distance from one end of said body with grooves or channels 6 6, which receive the opposite sliding ends of a transverse slide 5, that is pivoted at its center to the under side of top 1 by means of a pin 7, rigidly secured to top 1 and passing through the strip 5, its lower end having a retaining-pin 8. After the top 1 has been slid endwise for a convenient dis cover 1 across the other end portion of the table-body, thus completing the extension of the table and providing a table of twice the size of the original one. l/Vhen the top 1 is in its accustomed position upon the body 2, the tongue-pieces 10, a pair of which are secured to the under face of said cover at one of its end edges, willengage the sockets 9,

that are set into the body of the table or the. upper ends of the-legs 3, as shown in Fig.

6, the same being flush with the upper surface of said body, so as to leave no projecting points. Also this end of the top 1 is secured to the body 2 by means of some suitable catch or look devices, of which we preferably employ two, although we may use any number, and a preferred form of lock device that we employ we have illustrated in the drawings as an example, and we will now proceed to describe it. The detailed construction of one of these look devices is delineated in Figs. 4 and 5. On the upper edge of the end piece of body 2 is secured a flat plate 16, having a transverse slot therein. Beneath it on the inner face of said end piece is secured a Vertical strip 23, having an integral laterallygrooved projecting block 13, and in engagement with this block is a vertically-sliding slotted strip 14, having a slot through which .the block 13 projects and having also at its upper end another slot 15. Tensioned between the stationary block 13 and the lower end of the sliding strip 14 is a' spring 20, the 7 bearings, together with a spring 12 for foreing the bolt 10 endwise for the purpose of causing it to engage the slot 15 in the-end of strip 14- when the latter is lifted, thus lockin g the cover 1 to the body 2. By drawing the bolt 10 endwise in the other direction the bolt can be disengaged from strip 14, which will fly downward under the impulse of spring 20. As we have stated, we preferably use two of these catch devices on the end of top 1. we also provide the folded leaf 4 with a couple of them, which operate at the opposite end of the table, after the leaf 4' has been placed across the body, to hold the latter in position. The leaf 4: preferably has the pins 21 21, that take under the edge of top 1 to keep the adjoining edges of the two leaves close together. Also top 1 has a stop 22 to limit its rotary movement.

What we claim is 1. In an extension-table, the combination with the body having a leaf-receiving compartment and having also longitudinal side grooves in the interior of the body, of the table-top, a pivotal transverse bar carried on the under side of said top with its ends entering and slidable within the aforesaid grooves in the body, so that the said top may be moved endwise and then rotated into a position at right angles to the body, as set forth, a plurality of tongue-pieces securedto the under face of the cover, sockets formed in the tablebody to receive said tongue-pieces, and the hinged extension-leaf for completing the tatially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
